Abstract
The invention provides an optical device, including a light-transmitting substrate, optical means for coupling light into the substrate by total internal reflection, and a plurality of partially reflecting surfaces carried by the substrate, characterized in that the partially reflecting surfaces are parallel to each other and are not parallel to any of the edges of the substrate.

53. An optical device, comprising:
-
a display source emitting light waves; a selective diffuser for non-uniformly diffusing the light of the display source; an imaging optical module; a light-transmitting substrate having a light-admitting surface and at least one surface located inside said substrate for coupling the light out of said substrate; an optical coupler for coupling light waves from said imaging module into said substrate, and an output aperture for emitting light from the optical device, characterized in that light waves from the entire display source are coupled by the optical coupler via said light-admitting surface into the substrate by total internal reflection. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)
